Receiving a Message
When a message has been sent to you, you'll receive a generated email with a link to view the message on the counterpoint.cloud website.
With this email, you can click the "Go to CounterMessage" link if your email client supports links. If not, you'll have to copy and paste the text below the link into your browser to view the message.
Response Screen
Once you've either clicked the link or copied it into your browser, you can view the actual contents of the message. If you are the only recipient of the message and you have no yet replied, the bottom of the screen will allow you to provide an identity and response message.
However, if the message was sent to multiple people, only one person is able to reply. Therefore, you may see that someone has already replied, and the identity/message that they chose to respond with.
